Abstract: Techniques for a dynamic radar mode modulation feature are described herein. A computer system associated with a device may implement a first radar configuration for a radar sensor. The first radar configuration may correspond to a first mode and comprise a first frame per second rate and a first difference threshold. The computer system may receive first data from the radar sensor in the first radar configuration. The computer system may determine a presence of an object within a field of view of the radar sensor based on the first data and the first difference threshold. The computer system may instruct the device to turn on based on determining the presence of the user. The radar sensor may be instructed to implement a second radar configuration associated with a second mode.
